Title: Method and device for manufacturing semiconductor device
Inventor: HONDA TOSHIYUKI
IPC: H01L21/3205
Filed: 1984-06-15
Abstract: PURPOSE:To simplify the process of manufacturing semiconductor devices and to enable reduction of adhesion of dust consequent on the simplification of process by involving the process of removing the positive resist covering electrode leadout holes in the exposing process. CONSTITUTION:After an Si oxide film 11 is formed on both sides of an Si single crystal substrate 10 by thermal oxidation, one side of the Si oxide film 11 is spattered with Ti and Au respectively in succession to laminate a Ti-Au film 12 and then positive resist 13 is spread over said film 12. On the positive resist 13, a pattern 14 of a semiconductor device and a pattern 15 for an electroplating electrode lead-out hole are formed by development after irradiation with an electron beam by using an electron-beam drawing device. The substrate is immersed in a plating solution with a negative terminal of a constant-current source being in contact with the electrode lead-out hole 15 and the positive terminal with a metallic plate. Then this substrate is opposed to a sample and is energized so as to form a metallic pattern 16 followed by removal of the resist 13.

Title: Cooking container
Inventor: TOMOHIRO TERUHIKO
IPC: A47J27/00
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent excessive dryness and uneven heating of foodstuffs by equipping a cooking container with a housing and a lid and having a percolable water-absorptive section at least in a part of the housing or the lid. SOLUTION: A cooking container is equipped with a housing 6 and a lid 7, and the entire of the housing 6 and lid 7 is structured from a porous water- absorptive material. After the housing 6 and the lid 7 are saturated with water, a foodstuff is housed in there. When a microwave oven is heated, electric waves passing the water containing cooking container become weakened by being absorbed by the water. Accordingly, the electric waves acting on the foodstuff within the container are weakened as a whole, the water contained in the container is warmed, the temperature of the entire container is risen and the absorbed water is discharged as vapor.  Further, on the surface of the water- containing container reflective electric waves are generated and because of a mixed existence of a number of reflection-repeating electric waves whose phases are deviated, a uniform electric field can be obtained in which no resonant mode is difficult to be generated. As a result, a uniform heating can be performed with less heating irregularity.

Title: Telephone set separation detecting circuit
Inventor: USUI HISAYOSHI
IPC: H04B1/16
Filed: 1988-05-23
Abstract: PURPOSE:To make a cable exclusively used for detection unnecessary by detecting the DC potential of a speaker line, which is pulled down by the DC resistance component of a speaker when the state of a telephone set is a connected state and pulled up at a resistor when the state of the telephone set is a separated state. CONSTITUTION:When the state of a telephone set part 2 is the one in which the part 2 is connected through a cable 3 to a body part 1, the DC potential at a (b) point is pulled down by the DC resistance component of a speaker 10 and made into L. Further, a resistance R2 and a capacitor C2 to form an LPF eliminate a voice component. Consequently, a potential at an (a) point also becomes L, a comparator 15 sends an H voltage to a control part 6, and the control part 6 controls an operation when the state of the telephone set is the connected state. When the state of the telephone set part 2 is the one in which the part 2 is separated from the body part 1, the DC potential at the (b) point is pulled up at a resistance R1 and made into H. Consequently, the potential at the (a) point also becomes H, the comparator 15 sends an L voltage to the control part 6, and the control part 6 controls another operation when the state of the telephone set is a non-connected state. Thus, the cable exclusively-used for the detection becomes unnecessary, and the number of cables can be decreased.

The molten metallic Mg is flowed out from a conduit 25 by being carried on this convection and the gaseous chlorine is discharged from an exhaust hole 27. On the other hand, MgCl 2  is introduced from conduit 26 into the bottom part of the cell 7.

Filed: 1987-05-21
Abstract: PURPOSE:To make an input environment of an operating system (OS) flexible correspondingly to a user and to improve the efficiency of design by setting up a command analyzing function in a command processing system independently of the flow of the OS. CONSTITUTION:The syntax definition of a used command for a designed OS is entered in a knowledge base 101 relating to the syntax of a command. On the other hand, a command execution program is stored in a knowledge base 102 relating to the function of the command as a pair with a command name. An input processing part 103 executes preprocessing for analysis and the check of spelling of the command. A syntax analyzing part 104 extracts the command from an input character string and collates the extracted command with the syntax definition stored in the knowledge base relating to the command sentence. When a syntax error is generated in the input character string, the error is pointed out. When collation between the input character string and the syntax definition succeeds, a command program starting part 105 accesses a command execution program from the knowledge base 102 and a value is substituted for its argument to start the program.

Filed: 1988-05-20
Abstract: PURPOSE:To easily and rapidly detect cracks by wetting the surface of a refractory object with a volatile liquid, then visually observing the surface of the refractory object. CONSTITUTION:Evaporation of the volatile liquid 3 ends at the point of the normal part of the refractory object 1 having no cracks 2 and this point dries to restore the original color upon lapse of certain time after the surface of the refractory object is wetted with the volatile liquid 3. The volatile liquid 3 penetrated into the point of the cracks 2 hardly evaporates and therefore, this point is still wet. The cracks 2 on the surface of the refractory object 1 are detected as the part of the color changed by the wetting itself after the point of the time when the point of the normal part on the surface of the refractory object 1 dries when the surface of the refractory object 1 is visually observed after said surface is wetted with the volatile liquid 3.
